damn.
I forgot to mention the appearance lol, mc had silve/white hair and green eyes same with his daughter and ml has dark ahir and eyea. I think, I'm sure mc was a prime minister who secretly plotted something so big behind the crown and framed himself as a saint (even ml was fooled) Also did I mention his daughter was supposed to be a saint(she is) and was acknowledged by a dragon but she got replaced by the mistress of the crown prince (this mistress had a twin if i remember)
I'm in
I'm interested so I'm just gonna camp
I FOUND IT GOD GRACED MY MEMORIES (and after scouring my list) HOLY PULL

LET’S GOOOOOOOOO
So mc was reincarnated to a very high standing position i cant remember if it was soemthing like a marquis or count. He had a daughter who was engaged to a scumbag of a crown prince and he wanted to protect her from allat. He also has a son who is borderline siscon. Then there's this duke/knight that starts off opposing mc but gets gay for him. Its just so messy like i remembered how it goes but I cant put a pin on a summary for the life of me. All I can say is that mc might have been a villain in his prev life which is why he works so well as a villain in his current life. pls help
